To all whom it may concern:

Be it known that I, ABRAHAM N. WOLF, of Allentown, in the county ofLehigh and State of Pennsylvania, have invented certain new and usefulImprovements in Separators; and I do hereby declare the following tobe afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in separators for separating thedirt and germs from cracked wheat; and it consists in the arrangementand construction of parts, which will be more fully described andclaimed hereinafter, whereby a simple and very eliicient machine isproduced.

The object of my invention is to provide a machine by means of which thedirt and germs of the berries can be extracted from the crack ed wheat,and thus enable a better and liner grade of flour to be produced. l

Figures l and 2 are vertical sections of a machine embodying myinvention, taken at right angles to each other.

A represents a suitable frame, in which tl e separator-frame A isrigidly secured. This frame A may either be of the shape here shown orany other that may be preferred. Connected with this frameA at one endis the passage M, through which the cracked wheat passes into the frameA as it leaves the rollers or other mechanism by which it has beencracked, for the purpose of separatingthe germs of the berries and dirtwhich is in the creases from the cracked portions of the berries orwheat which is to be used in making our. Inside of this frame A isplaced the perforated stationary cylinder G, which may be madepear-shaped in cross-section, as here shown, or any other that may bepreferred. This cylinder is open at its apex, so that the direct suctionof the fan can be exerted upon the broken grain in the cylinder, andthus the light particles carried off without obstruction. The perfora`tions in this cylinder are just large enough to allow the germs of theberries and the dirt to fall through in the receptacle B below withoutallowing any of the broken portions of the berries to pass through atthe same time.

Passing through the frame A, the cylinder C, and the fanbox P is ahorizontal shaft, F,

which has secured to it a driving-pulleyJ, the

brushes D, wings E, and the suction-fan H. The brushes D are secured tothe outer ends of the'arms which project radially from the` shaft, andwhich brushes serve to force the germs and dirt through the perforationsin the cylinder, for the purpose of separating them from the crackedportions of the berries. The wings E, which are also secured to the armswhich extend radially from the shaft, consist of flat plates which areplaced at any suitable angle, and which serve to catch all the materialwhich is in the cylinder and throw it outward against the sides of thecylinder, and to raise it upward and drop it back upon the bottom of thecylinder, for the purpose of separating the coarse and fine particles,and to enable the suction o f the fan to catch all of the tine particlesand draw them away. The broken portions of the berries, after passingthe full length of the cylinder, are discharged through the spout K, asshown in Fig. 2. As these broken portions leave the inclined portion ofthe spout they are subjected to an upward draft from the fan H, for thepurpose of drawing away any of the line particles which may have passedthrough the cylinder.

In the upper portion of this spoutKis placed a valve or slide, Q, forthe purpose of regu-` lating the force of the draft.

In the frame A, just under the cylinder C, is placed theinverted-Vshaped deector R, which serves to contract the opening throughthe lower portion of the-frame A, and thus increase the force of thedraft at this point, for the purposeof drawing away any ne particles ofdirt and dust which may have been forced through the cylinder by thebrushes D. This upward draft catches the ne light particles of dirt andother impurities, and con- Veys them through the openings I, made in theupper portion of the frame A, to the fan H, from whence they are blowninto the dustroom or other suitable place. The suction of the fan H isalso exerted upon all of the particles in the cylinder C, not only whilelyingupon its bottom, but while dropping from the spout M, so as toremove the dirt and impurities and convey them to the dust-room.

IOO

VThe openings I in the frame are provided with' suitable slides orvalves, S, which serve tol regulate the force of the draft from the fan.By means of the construction above described all of the iine particlesof dirt are separated from the broken berries and conveyed away to thedust-room. Being unfit for flour, they are turned into feed. The germsand smaller pieces of the broken berries pass through the perforationsof the cylinder and drop into the receptacle B, whence they are carriedto the rolls to be made' into flour.

The seam-dirt and all other impuritiesV are thus separated from thegerms and broken pieces of the berries at the Very earliest possiblestage in the process of making flourviz., immediately after the firstbreak. By this means a finer and Whiter flour is produced than can bedone where this separation does not take place, as it is impossible toremove the dirt from the flour at the Iater stages of reduction after itis once ground fine and incorporated with the fiour.

Having thus described my invention, I ciairn- 25 lA separator composedof the frame A, provided with the air-passages I G, valves S Q, whichcontrol the passages and regulate the draft of the fan, the open-toppedperforated cylinder, the shaft F, carrying brushes and 3o Wings andhaving the fan secured thereto, the discharge-spout K, and the fan-boX,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ABRAHAM N. IVOLF.
